Unitary engine block having an intermittent contact intake and exhaust lifter system

Abstract

An intake and exhaust system for an internal combustion engine having a unitary engine block the system comprising a power cylinder, an intake lifter cylinder and an exhaust lifter cylinder that are formed integral with the engine block. This engine block has an intake port, and an exhaust port for allowing exhaust to flow there through. Inside the piston or power cylinder is a power piston which is driven by a crank shaft connected by connecting rod which extends through the power cylinder. This crank shaft is driven by a movement of the power piston which is caused by combustion of gasses inside the engine block. There is also a cam shaft which disposed within the engine block. This cam shaft is found on a top section of the engine block. Coupled to the cam shaft is a timing chain which is also coupled to said crank shaft. Thus, as the crank shaft rotates, it drives the timing chain which in turn rotates said cam shaft. To control the flow of exhaust gasses and the intake of air mixture, there is an intake lifter disposed in the engine block adjacent to the engine block intake port. There is also an exhaust lifter disposed in the cylinder adjacent to the exhaust port. To drive the intake lifter and the exhaust lifter, there is at least one oblong cam disc coupled to the cam shaft wherein this at least one oblong cam disc is for driving the intake lifter and said exhaust lifter intermittently so that exhaust can flow through the engine block from the intake port and out of the exhaust port.

       5. An internal combustion engine including an engine block and an oil pan the engine comprising: 
       a) at least one power cylinder disposed in the engine block and having a first end and a second end, said first end being coupled to the oil pan;  
       b) at least one intake cylinder disposed in the engine block adjacent to said at least one power cylinder and having at least one intake port;  
       c) at least one exhaust cylinder disposed in the engine block adjacent to said at least one power cylinder and said at least one intake cylinder and having at least one exhaust port;  
       d) a power piston disposed in said at least one power cylinder;  
       e) a crank shaft disposed in the engine block and extending through said at least one power cylinder, said crank shaft being driven by a movement of said power piston;  
       f) a cam shaft being disposed within the engine block, and extending through the engine block;  
       g) a timing chain being coupled to said crank shaft and said cam shaft wherein as said crank shaft rotates, it drives said timing chain which in turn rotates said cam shaft;  
       h) an intake lifter disposed in said at least one intake cylinder adjacent to said intake cylinder intake port;  
       i) an exhaust lifter disposed in said at least one cylinder adjacent to said exhaust port; and  
       j) at least one oblong cam disc coupled to said cam shaft wherein said at least one oblong cam disc is for driving said intake lifter and said exhaust lifter intermittently so that exhaust can flow through said intake cylinder and said exhaust cylinder from said intake port and out of said exhaust port;  
       k) a cover, coupled to said second end of said at least one power cylinder, wherein said at least one power cylinder is designed to form a single unitary engine block incorporating a cylinder head and an engine block in one single casting, and wherein said cover is removably secured to said at least one power cylinder such that said cover can be easily removable from said at least one power cylinder.
